This paper presents a modular multilevel converter (MMC)-based power electronic transformer (PET) for interconnection of solar photovoltaic (PV) system and the grid. The system under study consists of ...

Implement independent control of positive and negative half-cycle phase angles using separate trigger-time constant-setting ...

Transformer flux dc bias is a critical issue, impacting the reliable operation of dual active bridge (DAB) converters especially when ungapped high permeability nanocrystalline core is used. Steady ...
